Waveguide Pressurization Sections

Waveguide Pressurization Sections are straight sections of waveguide fitted with a Schrader Valve and calibrated gauge. When installed in a system they permit the waveguide to be pressurized with air or an inert gas. The units are pressure tested at 30PSIG. They are also available without the pressure gauge. See option note #5.


GENERAL SPECIFICATIONS

  • VSWR:1.08 max
    1.15 for WR 42 thru 28
  • Material:Aluminum
  • Flange Type:Cover / Cover Standard
  • Finish:ARRA Blue per MIL-C-22750

OPTIONS

1. For brass material, add B to basic model number.
2. Length may be modified. Replace last two digits with required length in inches.
3. For A cover/B choke flange, add -1.
     For A choke/B choke flange, add -2.
     For A choke/B cover flange, add -3.


4. For CPR or other flange, precede model number with flange type.
     Ex: CPR137G-290-04
5. For units without gauge, change the Series Number 290 to Series Number 295.
     Ex: 62-290-04 becomes 62-295-04 without gauge.
